Introduction
This document describes the steps necessary for the installation and configuration of a typical Semaphore for Solr solution.

It is recommended that as this guide is followed the relevant configuration details are completed in the Configuration Worksheet section of this document.
Audience
This document is intended for individuals responsible for the configuration of the Semaphore software suite within a Solr environment (typically Solr system integrators or software installation engineers). It is assumed that readers of this document have good understanding of the following:
- Microsoft Windows Server 2003 / 2008 administration (including installation and configuration concepts)
- Apache/Lucid Imagination Solr administration and general indexing concepts
A note about Semaphore versions
The Semaphore software is generally released as a suite of its various components. This entire suite is assigned a version number but within the suite the components also have their own specific revision numbers. Please see Semaphore Release Notes for details of the various versions of Semaphore.
Note that unless otherwise advised by Smartlogic, components from different suite versions should not be used as they may be incompatible with one another. For example, Ontology Server from Semaphore 3.2.1 and Publisher from Semaphore 3.3 cannot function together.
Important: Whenever issues are reported to Smartlogic always indicate the specific version of the software being used as this is required by the support team when investigating the issue.
